Treatment of Ag(CF3CO2) with an equivalent of bis(diphenylphosphino)amide (dppa) gave a tri- nuclear trigonal-bipyramidal silver(I) complex [Ag3(µ3-Cl)2(µ-dppa)3][CF3CO2]·CH2Cl2·H2O ([1]
[CF3CO2]·CH2Cl2·H2O). Reaction of AgNO3with an equivalent of dppa in the presence of [NH4] [GaCl4] and [Et4N][FeCl4] afforded the corresponding complexes [Ag3(µ3-Cl)2(µ-dppa)3][GaCl4]· 2THF·MeOH·H2O, ([1][GaCl4]·2THF·MeOH·H2O) and [Ag3(µ-Cl)(µ3-Cl)(µ-dppa)3][FeCl4], ([2]
[FeCl4]), respectively. Complexes1and2contain trigonal-bipyramidal [Ag3(µ3-Cl)2]+and [Ag3(µ- Cl)(µ3-Cl)]+cores, respectively, surrounded by three bridgingµ-dppa ligands.
